Khloe, who was traveling with her friend and longtime stylist Joyce Bonelli, was flying to the Big Apple ahead of her Good Morning America appearance on Wednesday.
A rep for McCarran International Airport in Las Vegas tells ET, "An American airlines flight 256 departed from LA en route to JFK. They called for an emergency landing due to concerns of smoke in the cockpit. The plane landed safely at 3:18pm and the alert was terminated (everything was found safe) at 3:27pm."
However, the rep could not confirm that Khloe was on this specific flight.
